Leech Lab


 



 



 


 

1.  What is the electrode measuring?

The electrodes are recording the electrical activity of the neurons.

2.  Why use leeches in neurophysiology experiments?

Leeches have very large, easily accessible neurons in their nerve cord and no one seems to worry about opening them up and feeling sorry for them.

3.  What is the difference between a sensory and a motor neuron?

Sensory neurons take nerve impulses from sensor receptors to the CNS and motor neurons take nerve impulses from the CNS to muscle and glands.

4.  Do you think a leech experiences pain?  What is pain?

Yes, I think leeches feel pain. They have a simple brain, a nerve cord, ganglia, and neurons. The have everything it takes to feel pain. They also have sensory organs on the head and body surface which enable them to detect light, temperature, and vibration.

Pain - For scientific and clinical purposes, pain is defined by the International Association for the Study of Pain (IASP) as "an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage".

Compliments of Wikipedia

5.  What were the two most interesting things about doing this lab?

I thought learning about the voltage inside of cells was interesting and the lab itself watching the poor little leech get cut up and its guts cut out.

6.  Anything you found confusing or didn't like about the lab?

I think for being an online lab, it was very informative, but I would much rather do this stuff in a classroom with other people, on real leeches.

Self Evaluation

REGARDING YOUR OWN PERFORMANCE

1. What were the three aspects of the assignments I've submitted that I am most proud of?

I am proud of all my assignments with all I have been through in the last month.

2. What two aspects of my submitted assignments do I believe could have used some improvement? I believe my graphs and tables could have been better, since I really had a hard time uploading them I was just grateful to be done.

3. What do I believe my overall grade should be for this unit?

I would be happy with a B, since I truly understand the work; I just have a hard time with blogger.

4. How could I perform better in the next unit?

I would like to be able to focus a lot more on school rather than cancer or surgeries. That will be my goal for this next unit.


REGARDING THE UNIT (adapted from Stephen Brookfield, University of St. Thomas "Critical Incident Questionnaire")

  1. At what moment during this unit did you feel most engaged with the course?

    I really enjoyed this unit right from the beginning and felt very engaged right from the beginning.

  2. At what moment unit did you feel most distanced from the course?

    I had quite a few struggles during this unit due to an unforeseen illness followed by a surgery. Which would be why I am turning in my work so late?

  3. What action that anyone (teacher or student) took during this unit that find most affirming and helpful?

    I am much appreciative to Mr. Frolich for his words of encouragement and allowing me to turn in my work late without a lot of pressure. He allowed me to focus on my health and didn't make it so terribly hard to get my assignments in on time. Thank You!!!

  4. What action that anyone (teacher or student) took during this unit did you find most puzzling or confusing?

    I don't think I found anything to be puzzling or confusing.


  5. What about this unit surprised you the most? (This could be something about your own reactions to the course, something that someone did, or anything else that occurs to you.)

    I was surprised by how much fun I had doing the metabolic lab.

A Healthier Diet, A Healthier Mind, A Happier World?

A healthier diet is a reward to our body and our minds, which in the long run rewards our communities and the entire world. Imagine a world of healthy living people. We would see much less sickness and much more happiness. Eating a diet rich in fresh fruits and vegetables gives our bodies the energy that these plants have sacrificed. The energy and life that resides in each living organism whether it be plant or animal is destroyed when we process it and put it in a box or a can to store on a shelf for years. All of the beautiful enzymes and nutrients that our bodies require for proper nutrition, digestion, mind function, and muscle coordination are lost when they are denatured by being over cooked and saturated with preservatives. Without venturing too far into the fact that the same thing is taking place with irradiating our meats, fruits and vegetables now, this is a topic of a different discussion. We will mainly just discuss the importance of fresh vegetables, fruits, and organic meats and dairy.

View Point 1: "A Life of not Knowing Any Better"

Growing up in a single parent home proper nutrition was a difficult task for my mother to achieve. I believe that money was not the true barrier in my mother's poor food choices; (although we were quite poor) I believe the main dilemma was a lack of knowledge in the importance of proper nutrition. Culturally, we came from a family of fast food eating, deep frying, mayonnaise loving people, so these habits were socially acceptable and no other thought was ever put into an alternative way of eating or cooking. Sure every now and again someone would hear on the news how bad a diet high in fat is, then the Atkins Diet would at the same time promote a diet high in fat and tell you not to eat the most essential carbs from fruits and vegetables. To this day most of my family including distant relatives still eats the same way because it's the only way they know. In the small town I come from there is not a nutrition class in the high school, nor would that even help if they are not taught the proper way of planning a nutritious meal. Needless to say along with the obesity I see a lot of unhappiness and depression in my relatives. Its seems no matter how hard I try to explain the importance of eating a diet rich in fresh fruits and vegetable and minimal meats and dairy it does no good. I had my mother stay with me for a month last year. While she was here, her diet was filled with good nutritious foods and I added some supplements which I thought might be helpful. She lost close to twenty pounds and her face beamed life once again. I thought wow; she will really enjoy feeling good and looking good and continue this life when she leaves….Nope, not at all. She has since regained the weight and the life in her face has subsided. Without looking for proof of how important the link is between my mouth and my spirit was shown to me through my mother's visit.

View Point 2 "Learning a New Way"

Although being raised on macaroni and cheese was the way I was raised, it is the opposite of the way I live today. I feel I have firsthand experience when it comes to the topic of nutrition. I used to eat whatever, when ever, and how ever much I could. I rarely added fresh fruit of vegetable to my diet. I had a diet of mainly processed foods high in fat and sugars. It never occurred to me that the hormones in my milk and meat may affect me in some way. I ate just like everyone else that I worked with, and I worked in a doctor's office where you think that nutrition would be first on our minds. Not by far! In fact it's been my experience that our healthcare workers are just as sick and unhealthy as the patients they are treating. That is, until I went to work in natural medicine. I became aware of the dangers that I was putting in my body day in and day out. I discovered a world of people that glowed in physical appearance and spiritual energy. The patients that came to this doctor didn't look ill, even if they were. The focus of the doctors concerns were always on the patient's diet and how much water they drank. I started paying attention. I first started by just cutting out most dairy products…I lost around 10 pounds in the first few weeks by just doing that. Then I began to eat more raw fruits and vegetables and cut out processed (poisoned) foods. That made a big difference in the energy I began to have and the way I felt in general. I choose to stick to more of a macrobiotic diet now. I can eat sushi every day and I come close to doing that. I eat only whole grains and rarely do I open a can or a box filled with processed foods in my house. One other thing I try to do is by only organic, sometimes it's just too expensive so I buy regular. I am hoping to grow my own garden this year…we will see how that goes. I no longer even think of eating fast food ( as a matter of fact it makes me ill), I never need a nap any more, I don't get frustrated as easily, I enjoy my life, and I rarely get sick. I choose to take supplements along with a healthy diet only because I feel that our food looses a lot of its nutrition if its radiated. The funny thing, if we listen to our bodies they tell exactly what they need and what is wrong if they are not filled with junk every day.

As I mentioned with my mom she was raised not knowing about the importance of nutrition. I wasn't raised with that either, but I was fortunate enough to become educated on its importance and believe in it, she didn't believe in it. As they say, "you can lead a horse to water, but you can't make him drink." I feel that most of the population doesn't even know there's a water trough. I feel we should make more of an attempt in educating our society about processed foods, refined sugars and flours and how dangerous these things can be to our body. Proper nutrition is crucial in how we feel emotionally and spiritually. This is why in some areas they treat depression or the so called ADHD with amino acid therapy and diet changes first and they have very good outcomes with just changing that. Our bodies are so important that we spend inconsiderable amounts to cover them in name brand clothes, pay excruciating amounts to haul them around in cars, but to think of spending a little bit more for fresh organic or local foods in unfathomable. With industrialization we have eliminated the appreciation and the importance of the food we put in our bodies. Starting at the elementary age we should incorporate programs such as the farm to school programs, give incentives for families to grow gardens once again, bring back the local farmers. Nutrition classes and disease awareness classes could be considered in our high school right alongside of sex ed. If we can teach our children about homosexual behaviors in school, then I see no problem teaching them about taking care of their body with the right foods. Whatever it takes to teach this new generation that the way things are being done right now are WRONG. Things must be changed or we will have an ugly, sick, and unhappy world of people.

Lab Write Up



Activity 1
Pre Hyperbaric Treatment and the Hyperbaric Treatment

Activity 2- Hiking
Hiking Thunder Mountain and Hiking Chimney Rock Trail


Activity 3 Walking
Walking Flagstaff With Nicholas and a Great Sunset during one walk


Introduction: In this lab I will show the results of various activities and the impact they have on the body's metabolic system. I will compare my baseline vitals at rest to my vitals concluding 3 different activities.


Hypothesis: I hypothesize that I will have no change in vitals, although I will be fully saturated with oxygen in my first activity. In my second activity I believe that my pulse rate will increase to at least 2 times, maybe 2.5 the normal rate. My respirations will also increase quite a bit and my systolic blood pressure will probably rise a bit, but not much. The third activity, I think my respirations will rise slightly and my heart rate will increase some.


Materials:

Stethoscope

Blood Pressure cuff

Co-worker

Husband

Mother Earth

Methods: My first activity was done each day for a week at work. My coworker took my vitals after each hyperbaric oxygen treatment. I was taken to 2.4 ATA (which is 45 feet under seawater) for 130 minutes. In my second activity I was doing my usual hiking trails at various elevations and speeds. The third activity I used my nightly walk. My vitals were taken by my husband for the second and third activities.

Data: Table available on next post/graph unable to load

METABOLIC RATE DATA TABLE

Analysis of Data: My hypothesis was correct in all three activities. I saw my vitals remain the same in activity 1, rise quite a bit in activity 2, and slightly with the activity 3.

Problems with Data: I believe that the data was a rough sketch as to the true metabolic changes that take place during various activities. If I were to do this again I think it would be fun to include body temp, blood sugar, O2 level, and hydration levels through specific gravity levels.

Conclusion: In this lab I really began to think of the metabolism that takes place through proper nutrition, exercise, and rest. When I was doing all of these activities (especially #2 when I was on the top of thunder mountain) I could imagine the internal respiration taking place in my body with my red blood cells carrying the oxygen to my capillaries and tissue and the each red blood cell taking back the carbon dioxide and waste to my lungs for external respiration to occur. My respiratory rate was increased so I could keep up with the increased cardiovascular system. With my blood circulating faster my temperature went up increasing the size of my blood vessels. All of these things working together maintaining homeostasis…what a beautiful thing. I had a great time doing this lab and look forward to doing the next one.

-How healthy a daily diet do you think this is? Why?
On a daily basis I would say I have a fairly clean and healthy diet. I try to eat plenty of organic fruits and vegetable (the entire rainbow of colors) along with lean meat and whole wheat grains and olive oil. I don’t eat a lot of dairy. I still eat yogurt and cheese but not a lot. I try every day to drink 4 liters of water because I think water is so important for my overall health and endurance. I used to eat fast foods and refined products until around 2 years ago when I learned how important nutrition is. I can’t imagine ordering from a drive thru now.

-What would you change about this day's eating, if anything?
If I were to change one thing in this days eating it would be the coffee. Coffee is my one vice that I still love doing, but I am not ready to give that up yet.

-Do you find this kind of nutritional tracking helpful? Why or why not
I think seeing anything in black and white puts a new twist of reality to it. So, yes I think tracking your eating habits is a very useful tool.
